Description: Archaeobatophora typa n. g. and sp. of the Upper Ordovician, Richmondian Big Hill Limestone from Delta County, Michigan, is described as a member of the Dasycladaceae. Although this alga is only weakly calcified along its main axis, its morphology is unusually well preserved and allows assignment to the extant tribe Batophoreae.
